Abstract: A device (70) for evacuating people from a building is provided with a rescue member via which people can be brought from an upper storey of the building (2) to ground level (28). The rescue member has at least one rope (20), belt or similar, which is let down from the upper storey of the building (2) along the building wall to ground level (28). At specified intervals on this rope (20), support members (31) are arranged with which, in each of the storeys, a carrying element (32) can be connected, on which at least one person is held. The carrying elements (32) are automatically detachable in an area close to ground level (28). This device (7?) enables people to be evacuated safely and easily.

Abstract: A pipe seal connection defines the seal between confronting pipe ends of two pipes which are coaxial and rotatable relative to each other. The confronting pipes ends are provided with spaced conical surfaces forming therebetween an annular slot which widens radially outwardly. An annular seal ring is positioned within the annular slot. A clamping band circumferentially surrounds the annular sealing ring and presses the sealing ring radially inwardly into contact with the spaced conical surfaces.

Abstract: A refractory plate assembly for use as a stationary or a movable refractory plate in a sliding closure unit includes a refractory supporting body and a refractory disc-shaped member forming a sliding sealing surface of the assembly. The disc-shaped member is loosely and removably mounted to the supporting body in a manner to prevent the disc-shaped member from working loose from and moving relative to the supporting body.
